William G. Wilhelm, 60, of La Jolla passed away on Monday, March 11 surrounded by his loving family.

He was born to the late John and Rose Marie Wilhelm on May 9, 1952 in La Jolla. Bill, the third of five children, graduated from the University of San Diego and California Western School of Law. After practicing law for a number of years, he became interested in the research and development for several of his father’s inventions in addition to some of his own, namely the navigational software Micro Mariner. In 2008, he became involved with AquaLogix, a firm that manufactures fitness equipment used by many YMCAs, gyms and also for the rehabilitation of Wounded Warriors. He was proud to be named president of the company in 2009. Bill also continued to practice law, specializing in business licensing and technology startups.

In 1954, the Wilhelm family, which included John, Rose Marie, Diana, Jack and Bill moved to Majorca, Spain for one year. Much to his parent’s delight, little Bill became quite proficient in the Mallorquin language. In later years, he continued to take advantage of “the travel bug” by enjoying trips to Costa Rica and Mexico and hiking throughout many parts of Southern California. La Jolla, however, held a special place in his heart. To him, there was nothing like the beach, be it Windansea or the Cove — he loved it all.

Bill is survived by his loving wife of five years, Judy Wilhelm; brothers and sisters Diana Carter, Jack Wilhelm, Michele Perry and Rick Wilhelm; in addition to a number of nieces and nephews.

As many of his friends can attest, once you met Bill, he was your friend forever. A celebration of his life will be held on Saturday, April 6 at the home of Bo Fellows in La Jolla.
